Lady Gaga canceled a sold-out concert in Indiana last night after collapsing shortly before taking the stage.

The “Bad Romance” singer had to pull out of the Purdue University performance on her Fame Monster Tour after paramedics discovered her heart was beating irregularly, reports Popcrunch.

“Due to exhaustion and dehydration, Lady Gaga collapsed and passed out before her show tonight in West Lafayette, IN. Her physician has advised her to take a few days off to rest,” a rep for the singer told The Insider.

The eccentric artist will makeup the canceled gig on Jan. 26. Meanwhile, she reached out to her fans, apologizing over Twitter.

“I hope you can forgive me. I love my little monsters more than anything, you are everything to me…..”
